Server which is good for me
 

Hostsailor.com and hostwebis.com servers seem to be good for me and I wonder which plan I should sign up with to host a forum?

It seems to me servers from hostingsource.com and kvchosting.net can be suitable for all your needs.
These guys provide fast international network, friendly technical support and 100% customer satisfaction.

They have a live chat feature that's very useful for real time problem solving.
I am happy using kvchosting.net service. And for what you get, the prices are fantastic.
Lots of features!

A server which is used for better security purpose for the data collections.

Saving one or two dollars per month is not worth the loss of a few hundred or a few thousand dollars when your site goes down.

==>> great server packages offered by Okayservers.com and their professionals.
Find out what is reasonable for your needs and pick something that will support your site on into the future.
